Key Features & Technical Highlights
Dual MPPT for LV Three-Phase Systems
The SUN-18/20/21K-G04-LV series incorporates two independent MPPT trackers optimized for low-voltage three-phase grid connections. Each MPPT supports 3 strings (3+3 configuration), enabling flexible array designs across different roof orientations or partial shading scenarios.
With a wide MPPT voltage range of 200V to 700V and rated DC bus voltage of 350V, the inverter accommodates various string configurations while maintaining peak efficiency on LV 127V/220V and 133V/230V networks.
Industry-Leading Efficiency
Maximum conversion efficiency of 98.6% combined with MPPT tracking efficiency exceeding 99% minimizes energy losses throughout the system lifetime. This high efficiency directly translates to improved energy yield and faster return on investment for commercial installations.
Comprehensive Protection Suite
- DC Side: Reverse polarity protection, surge protection (Type II), integrated DC switch
- AC Side: Overcurrent, overvoltage, and short circuit protection with Type II surge protection
- System Safety: Anti-islanding, residual current detection, insulation impedance monitoring
- Thermal Management: Intelligent air cooling with automatic derating above 45°C
- Optional: Arc Fault Circuit Interrupter (AFCI) for enhanced fire safety
Smart Monitoring & Grid Support
Standard RS485/RS232 communication ports with optional GPRS, WiFi, Bluetooth, 4G, and LAN connectivity enable comprehensive remote monitoring.
